Patent attributes
A manipulator system 10 comprises a manipulator 14 which includes two pairs of adjustment screws 18a, 18b and 19a, 19b, which can be used to displace a lens group assembly 11 relative to the longitudinal axis of the manipulator when the lens group assembly 11 is inserted within the manipulator 14. The lens group assembly 11 comprises a holder 22 in the form of a hollow, cylindrical tube that has mounted in two lenses 12, 13. The holder 22 has a throughbore through which a laser beam may be passed in use. The manipulator system 10 can be used to adjust the tilt and displacement of the holder 22 (and hence of the pair of lenses 12, 13). Such adjustment will cause a laser beam passing through the manipulator system 10 and holder 22 to have, e.g., a particular pointing direction and shape when exiting the lens group assembly 11.
